unobtrusively show your own dest ID in I2PSnark

Description

I think it would be nice if I2PSnark would show one's own I2PSnark truncated hash Dest ID (such as a~Rj, gA7f, etc.) somewhere in the main interface. Perhaps in the same line as the "Totals:" text beneath the list of torrents.

I think this would help users to understand better how dests work and what they're seeing when they open the "peer" view in I2PSnark. It would also be helpful for those who have their tunnels configured to change keys from time to time, to allow them to verify that a new key is in use.

Assigning this to self as a result of discussion a few releases ago with zzz.
I have code locally for this and I will be testing it to ensure it looks OK, then checking it in within the next 24 hours - to not cut it too fine with the release.
